Application filed September 28, 1910. Serial No. 584,317.

T 0 all whom it may concern:

Be it known that I, DAVID WV. PATTERSON, a citizen of the United States,residing at Helena, in the county of Lewis and Clark and State ofMontana, have invented a new and useful lVheeLMounted Scoop, of whichthe following is a specification.

This invention has relation to wheelmounted scoops and consists in thenovel construction and arrangement of its parts as hereinafter shown anddescribed.

The object of the invention is to provide a portable scoop which in turnis provided with a pivoted bottom, the pivotal point be ing in thevicinity of the forward end of the scoop.

Means is provided for raising and lowering the forward end of the scoopwhereby the forward edge of the bottom may be used as a scraper or earthcutter when the scoop is being loaded. A lever mechanism is provided forswinging an arch axle which in turn raises or lowers the forward end ofthe scoop and a locking device is provided for holding the rear endportion of the bottom of the scoop from swinging in a downward directionwith relation to the body of the same.

In the accompanying drawings ;Figure 1 is a side elevation of the scoopillustrating the bottom of the same in open position. Fig. 2 is a topplan view of the wheelmounted scoop. Fig. 8 is a side elevation of thescoop illustrating the position of the parts when the scoop is about totake in a load. Fig. 4 is a rear end elevation of the scoop.

The scoop consists of an axle 1 which is provided with an intermediatearch or crank portion 2. Supporting wheels 3 are journaled upon the endportions of the axle 1 and an open center frame 4 is also supported uponthe end portions of the said axle 1. A draft tongue 5 is attached to theforward end of the frame 4. A platform 6 is fixed to the rear end oftheframe 4 and an operators seat 7 is mounted upon the said platform. Arod 8 passes transversely through the rear portion of the frame 4 fromside to side thereof and a scoop 9 is provided in its side with a seriesof perforations 94 which are adapted to receive the said rod 8 wherebythe said scoop may be adjusted in position with relation to the frame 4.Links 10 pivotally connect the forward side portions of the scoop 9 withthe upper intermediate crank portion 2 of the axle 1. A lever mechanism11 is mounted upon the platform 6 and a rod 12 operatively con- I nectsthe said lever 11 with the intermediate portion 2 of the axle 1. Anysuitable means may be provided for holding the lever 11 in an adjustedposition. By this arrangement of parts it will be seen that by swingingthe lever 11 and moving the rod 12 longitudinally, the intermediateportion 2 of the axle 1 will be swung upon the ends of the said axle asan axis and the link 10 will be moved longitudinally whereby the forwardend portions of the scoop 9 will be swung vertically upon the rod 8 as apivot.

The scoop 9 is provided with a bottom 13 which in turn consists of aplate having at its forward end and at its side upturned lugs 14, whichare pivotally attached against the outer surfaces of the sides of thescoop 9. A pin 16 is secured to the rear edge of the pivoted bottom 13at a point intermediate the side edges thereof and the lower end of abar 17 is pivoted upon said pin 16. The bar 17 is provided at its upperend with a rearwardly disposed handle 18 and at a point between its endswith a notch 19. A pin 20 is mounted upon the rear side of the scoop 9and at times is adapted to enter the notch 19 of the bar 17 whereby thesaid bar 17 is held in an elevated position and the bottom 13 is heldclosed against the lower edges of the scoop 9.

In operation the scraper is used as follows. When it is intended to movefrom one point to another upon the surface of the ground the lever 11 isswung so that the intermediate blank portion 2 of the axle l is held inan elevated position as shown in Fig. 1 of the drawing. Thus the forwardend portion of the scoop 9 is held in a position elevated above thesurface of the ground and the scraper may be readily moved from point topoint. When it is desired to load the scraper with material at thesurface of the ground, the lever 11 is swung so that the intermediateportion 2 of the axle 1 moves in a downward direction when the forwardedge of the bottom 18 of the scoop 9 will come in contact with thesurface of the ground and as the scoop is moved along the ground thematerial is banked up in the rear portion of the scoop. When the scoophas been filled the lever 11 is swung in a rearward direction wherebythe intermediate portion 2 of the axle 1 is elevated and the forwardportion of the scoop 9 is elevated and the material thus loaded upon thescoop may be transported to a point where it is desired to dump thesame. In order to dump the same the operator engages the rearwardlydisposed portion 18 of the bar 17 and swings the said bar to one sidewhereby the notch 19 thereof is disengaged from the pin 20 at the rearedge atthe rear side of the scoop 9 and thus the rear portion of thebottom 13 is free to swing which it does under the weight of the loadcarried by the scraper as the material may pass out of the body of thescoop 19 below the lower edges thereof andv above the rear portion ofthe bottom 13. As the rear portion of the bottom drags upon the surfaceof the ground the material which escapes from the scoop 19 isdistributed or spread upon the surface of the ground.

Having described the invention what I e] a im as new and desire tosecure by Letters Patent is l. A scoop comprising an arched axle,supporting wheels journaled upon the ends of the axle, a frame mountedupon the ends of the axle, a lever mechanism mounted upon the frame andoperatively connected with the arch of the axle and adapted whenmanipulated to turn the said arch in the axle upon its end as an axis, ascoop pivotally mounted upon the rear portion of the frame and meansconnecting the forward portion of said scoop with the arch of the axle.

2. A scoop comprising an arched axle, supporting wheels 'journaled atthe ends thereof, a frame mounted upon the ends thereof, a lever mountedmechanism mounted upon the frame and operatively connected with thearched portion of the axle to swing the same, a scoop pivoted at therear end of the frame, links connecting the forward portion of the scoopwith the arched portion of the axle, a bottom p'ivotally attached to theforward portion of the scoop. and a latch mechanism for holding the rearportion of the bottom closed against the scoop.

3. A scoop comprising an arched axle, supporting wheels journaled at theends thereof, a frame mounted upon the end portions of the axle, a levermechanism mounted upon the frame and operatively connected with thearched portion of the axle, a scoop adjust-ably pivoted at the rearportion of the frame, and links pivotally connected at their forwardends to the scoop and at their rear ends to the intermediate archedportion of the axle.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
